Ultimately, it is a combination of these three factors:
- How much DPS can you put out, because sometimes there will be no one else supporting.
- How strong are your single target heals, your raid/aoe healing and the buffs you have available.
- How resistant to being killed are your toons, in a 5x same class environment.



Druids have the advantage of already being 85th.
Some of their Feral Honor gear can be used as Resto, but most of it will likely be worse than a few hours of quest green gear in Twilight Highlands (have not done any quests there with the Druids).
Could possibly spare two talent points for Cat Speed + 4x Feral PvP bonus (Cat/Bear/Travel +Speed); and stealth can be good at times.



Priests can glyph Fear Ward, making it one minute duration, one minute cooldown.
And then mass dispel any aoe fear.
I have had marginal success with that; making them stronger vs AoE fear than Pallies/Druids but weaker then Shammies.
I really liked the Cata changes to Disc Priests, during the 68-75 level up process.



Pallies so far have nothing for AoE heals, except perhaps their Cone heal (last point in Holy).
Everything I've read suggests it is fairly useless.
I already have the Pallies set to heal their Focus if they have a Focus, and can independently set their focuses; so while there isn't the AoE heals, they can single-target heal five different toons in a mass melee.
And receive fairly decent self heals in the process.
One school of magic for all offense/defense is a detraction; the lack of Holy Resist is a huge plus.



Anyone know if the Tremor Totem is party-wide or raid-wide?
I don't like the general lack of mobility, and the need to be a turret.
But Tremor (if it is raid wide) is near fear immunity.
Grounding on round-robin is spell protection.
Fire Elementals every 5 minutes has always rocked in battlegrounds.
